Note:
Alarm input and axis enable output are used as general input and output at the same time,
when it is output, output small current.
ECI3828 differential pulse axis and differential encoder input are only for axis 0 and axis 1.
Axis 2 and axis 3 are low-speed single-ended pulse interface OUT2-3, which can be modified
to take effect through ATYPE.
High-speed single-end encoder input of axis 2 is IN0-2, low-speed single-end encoder input
of axis 3 is IN21-IN23.
